I've been tracking my weight fairly consistently from age 17-31 using the iOS app "Lose It!" which I also have used off and on to count calories while trying to lose weight. I exported the data to CSV from their website and created the visual in Google Sheets.

ETA: 31M, 5’ 9.5”

ETA2: Here's a version with age instead of date. It messed up some of my data labels and I didn't feel like taking the time to reset them and tediously redelete most of them so there's no weight labels on the main peaks/ valleys like the original.
